engine swap

[bobfil]

I would like to know can you do an engine swap from a motor from an automatic car into a car that is already a 4 speed? The automatic motor is 70 - 77 454, going in to 72 vette 350 4 speed. What parts are required? Thanks for any help, Bob.

Be sure the new motor has the hole drilled and tapped on the side of the block for the clutch cross shaft.

Besides bobfils crossshaft hole and although its been decades since I messd with 1970s GM manual transmission cars, but I seem to recall that theres a bushing to drive into the rear of the crank too

Could that be for throw out bearing?

The 454 should have the hole for the clutch cross shaft. It's the same parts which are already on the car with the 4-speed in it.

You need a 454 flywheel.
You need to fit the crankshaft with a pilot bushing.
You'll probably want a different clutch, a new disc and a T.O. bearing.
